STOP-MOTION FOR RING-SPINNING FRAMES.

SPECIFICATION forming part of Letters Patent No. 777,918, dated D r 20,1904.

Application filed April 26, 1904.. Serial no. 204,972.

To all whom it may concern:

Be it known that I, Josnrn PoIssoN, a citizen of the United States,residing at Fall River, in the county of Bristol and State ofMassachusetts, have invented a new and useful Improvement inStop-Motions for Ring-Spinning Frames, of which the following is aspecification.

This invention has reference to an improvement in ring-spinning frames,and more particularly to an improvement in stop-motions forring-spinning frames.

Builder-motions of spinning-frames as constructed are liable to buildthe thread on the bobbins beyond the top of the bobbins before stoppingthe frame, thus causing loss in time and waste of material.

The object of my invention is to positively and automatically stop thespinning-frame when the builder-motion has built the threads on thebobbins to the required height, and I accomplish this object by the useof my improved stop-motion, which is operated indirectly by thebuilder-motion to throw the belt-shipper of the machine.

A further object of my invention is to provide an adjustable stop-motionwhereby the stop-motion is easily and quickly adjusted for differentheights or lengths of bobbins.

My invention consists in the peculiar and novel construction of astop-motion for ringspinning frames, said stop-motion,consisting of afixed collar and a sliding collar on the shipper-rod, a coiled springattached to the sliding collar and to a fixed part of the machine, anarm pivotally secured to the sliding collar and having a notch adaptedto catch on a fixed part of the machine and hold the sliding collar inits normal position against the tension of the coiled spring, a Verticalrod pivotally secured to the free end of the notched arm, an adjustablestop on the vertical rod, and a lever secured to a rock-shaft in aposition for its free end to engage with the adjustable stop on thevertical rod, said lever having a movement coinciding with the rockshaftlifter-arm and the ring-rail and other details of construction, as Willbe more fully set forth hereinafter.

' Figure 1 is a front view of a ring-spinning 5 j frame provided with myimproved stop-m0- tion, showing the greater portion of the machine onthe right broken away to clearly show my invention. Fig. 2 is a detailplan View of the shipper-rod, shipper, drivingpulleys, and the adjacentportion of the frame and cross-strut; and Fig. 3 is a detail plan viewof one of the rock-shafts of the machine to which my improvedstop-motion is operatively connected. ()0

In Fig. 1 the essential elements of a ringspinning frame with which myimproved stopmotion cooperates are shown. These consist of the end framea, the main shaft to, the fast pulley (f, the loose pulley a the shipper(4*, 5 the shipper-rod a the top rail a, the ringrail (4 thebolster-rail a the lower side rail a, the bracket a the rock-shaft a,the rockshaft lifter-arm (0 the lifting-rod a, the Weighted arm a, theoperating-arm (L15, and 7 the chain a, operatively connected with thearm (0 and the usual builder-motion. (Not shown.)

In applying my improved stop-motion to a ring-spinning frame thecross-struts b and c are secured to the top rail The strut b has thebearing 6 for the shipper-rod a and the lug 6 The strut c has thebearing 0 for the shipper-rod and the lower extension 0 in which is theopening 0 as shown in Fig. 1. The fixed collar (Z is adj ustably securedto the shipper-rod c by the set-bolt d, intermediate the struts b and 0.The sliding collar 0 is supported on the shipper-rod intermediate thefixed collar (Z and the strut 0, adjacent the 5 fixed collar, and hasthe lug '6, connected to the lug by the coiled springf. The arm 9 ispivotally secured to the lug e on the sliding collar (1 and extendsthrough the opening 0 in the lower extension of the bearing 0. The 9free end 9 of the arm 9' has the notch adapted to engage with the loweredge of the opening 0 in the extension 0 and hold the sliding collar 0in its normal position against the tension of the coiled spring f. Thevertical rod h is pivotally secured at its upper end to the free end ofthe arm g and has on its lower end the stop it, which is adjustablysecured to the rod by the set-bolt k Thelever't' is secured to therock-shaftrt by the bolt '0" and has in its free end i the slot throughwhich the lower end of the vertical red It extends, with the stop itabove the free end of the lever '5.

In the operation of my improved stop-motion for ring-spinning frames thestop it is adjusted and set on the vertical rod [2, for the height ofbobbins used. The rock-shaft a is operated through the chain a by thebuildermotion in the usual way. The lever i moves in unison with thelifter-arm (4 the liftingrod a, and the ring rail a When the threads arebuilt on the bobbins to the required height, the free end of the leverr; engages with the stop it and lifts the rod it and the free end of thearm g and raises the notch 5/ out of engagement with the lower edge ofthe opening 0. The sliding collar 6, by the tension of the springf',engages with the fixed collar (Z on the shipperrod and moves the shipperfrom the fast to the loose pulley and stops the machine. The operationof starting the spinning-frame by moving the belt onto the fast pulleyin the usual way moves the parts of the stop-motion back into theirnormal or operative position.

By the use of my improved stop-motion on ring-spinning frames any lengthof bobbin may be used in the frame without reference to the complicatedmechanism of the buildermotion, waste of material in overbuilding thethreads on the bobbins is eliminated, and a better result is attained inthe completed bobbins than has heretofore been done.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a spinning-machine, the combination with abelt-shipper, a shipper-rod, a collar secured to the shipper-rod, asliding collar supported on the shipper-rod, a spring connecting thesliding collar to a fixed part of the machine, an arm pivotallysupported on the sliding collar and provided with a notch adapted toengage with a fixed part of the machine, of the builder rock-shaft, alever secured to the builder rock-shaft, and a connection between thearm and lever adapted to release the arm at a predetermined time, asdescribed.

2. Astop-motion for spinning-frames having a fixed collar and a slidingcollar on the shipper-rod, a coiled spring attached to the slidingcollar and to a fixed portion of the machine, an arm pivotally securedto the sliding collar, a notch in the arm adapted to catch on a fixedpart of the machine and hold the sliding collar against the tension ofthe coiled spring, a vertical rod pivotally secured to the free end ofthe notched arm, an adjustable stop on the rod, a builder rock-shaft,and a lever secured to the builder rock-shaft in a position to engagewith the stop on therod, as described.

3. The combination with a spinning-frame of a stop-motion consisting ofa cross-strut 5 having the bearing 6. and the lug 6 a crossstrut 0having the bearing 0 and the lower extension 0 in which is the opening 0a fixed collar (Z having the set-bolt (Z, a sliding collar 6 having thelug a connected to the lug b by the coiled springf, an arm 9 pivotallysecured to the lug e and having the free end 9 in which is the notch 9 avertical rod IL pivotally secured to the arm 9 and having the adjustablestop 72/ .with the set-bolt if, and a lever t' having the set-bolt '6and the free end in which is the slot f, as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOSEPH POISSON.
